Cluster Membership Monitor

To ensure that data is safe from corruption, all nodes must reach a consistent
agreement on the cluster membership. When necessary, the CMM coordinates a cluster
reconfiguration of cluster services in response to a failure.

The CMM receives information about connectivity to other nodes from the cluster
transport layer. The CMM uses the cluster interconnect to exchange state information
during a reconfiguration.

After detecting a change in cluster membership, the CMM performs a synchronized
configuration of the cluster. In this configuration, cluster resources might be redistributed,
based on the new membership of the cluster.
